// Description:
//          This event is fired when the application starts  - once that application�s Run() 
//          method has been called. 
//
//          The developer will typically hook this event if they want to take action at startup time 
//
// History:
//  08/10/04: kusumav   Moved out of Application.cs to its own separate file.
//  05/09/05: hamidm    Created StartupEventArgs.cs and renamed StartingUpCancelEventArgs to StartupEventArgs
